Some important simplifications for classification were failing to fire because other simplifications fired first, short circuiting the search. It turns out that more than one rule may apply at any given step (and it is important to apply all of the rules that can be applied). This commit modifies the simplifier to apply rules until saturation. |

Overview
The tests in this directory attempt to test both ARM and Thumb decoding/discovery. The test suite only runs on the binaries with corresponding .mcw.expected files, which describe the expected discovered basic blocks.
- test-just-exit-a32.exe: Ensures that the very basics of anything at all works
- test-conditional-a32.exe: Ensures that conditional branches in A32 mode are handled correctly
- test-direct-call-a32.exe: Ensures that call and return sequences work in A32 mode
- test-direct-call-t32.exe: Ensures that transitions (via call) to Thumb mode work correctly
- test-conditional-mixed.exe: Ensures that multi-block Thumb functions are handled correctly
- test-just-exit-t32.exe: Ensures that Thumb entry points work correctly
Notes
The test-just-exit-t32.exe test is interesting because executables with Thumb entry points have the low bit set (even though it isn't technically the address where the function starts - it happens to work because the ISA clears the bit before jumping). We want to make sure that macaw handles it correctly.
